The presentlnventlon pertains to stoves, ranges andthe like, and moreparticularly toan improved construction of the oven thereof.

It'is an object of the tide an air vent arrangement for an oven chamherwhereby cooking vapors of relatively high temperature are vented into asecond compart-- to he slowly dissipated to the atmosphere L variousopenings of the compartment which ere not sealed in air tight relation.

it is another object of the present invention. to l "e a ventarrangement for an oven chamber is simple in construction, economical ofmature and highly efiioient in use. i

mp-srtment ferthe interposition present invention to pro ioh aresliolably mounted at to the rear side of The sides, top and bottom wallsof the liner '44 extend forwardly through an opening in the front wallof the range and is marginally flanged, as at 49, to overlie the edge ofthe front an access opening to the chamber 45.

The opening 50 is closed by a. suitalgle door 52 comprising :in outerpan 54 and an inner pan 56 held in spaced apart relation with heatinsulation material 51 therebetween. The door is hingedly mounted to thecabinet at so as to Swing downwardly into a horizontal plane. The hingesare of the concealed type and co nprise an axially movable hinge pin 60slidably mounted in a U-shaped member 8! whioh'ls secured to the outerpan 56 to lie between the outer end inner pan of the door. The pin 60extends through an opening in the side wall of the outer pan to hejournalecl in a, lug member 62 which is secured to a. supporting platemember 64. The mete member so is secured by weld or the like the frontwall 32, with the lug member projecting outwardly through an openillg inthe front well the door between the side walls of the inner end outerpan.

The hlnging of the oer 52 is so arranged that the top is swung past thevertical center of the hinge pin so that the ten of the elem restsagainst the edge of the ciooz 'opening an sealing relationship therewithto prevent en trance of air therethrongh into the oven ehamheii Thebottom portion of the door is spaced; from panel forming itsIowergcorners' for inning the door to olosed peesit/ion, one end efiixedto an ereuete arm- "FQQanol its opposite to plate member Gt ere theopening to provide a restricted 'prior to circulation in chamber 45adapted for heating the circulating air therein. A second heatingelement 82 is secured adjacent to the top wall of the oven chamberadapted to serve in pre-heating the chamber, and for broiling. A baiiiemember 94 is supportingly secured to and over the heating element 90adapted to direct the circulation of air over the heating element 90.The baflle member 84 and heating element 80 are arranged relative to theopening 15 so cold air over the heating element to be heated the ovenchamber. An outlet vent is provided for venting vapor from the ovenchamber comprising a tubular member 96 extending from the oven chamberinto compartment 38 forming a communicating passageway 91 therebetween.I

By the present arrangement cold air is drawn into the oven chamberthrough the restricted passage 15, directed by the baille member towardsand heated by the heating element 90 prior to its circulation in theoven chamber. Cooking vapors and steam arising from the use or bakingoperation in the oven chamber is vented through the passageway 91directly into the compartment 35 where it is cooled and difiusedto theatmosphere. Atmospherical air circulates ireely through the compartmentas no seal is provided by the drawers around the drawer openings, or thesurface units, and an opening Hill is provided in the rear wall of thecabinet. It will be noted that the vent is positioned to discharge thestream of vapors from the oven chamber adjacent to the rear portion ofthe compartment 3.. As the temperature of the discharging vapors isrelatively high it is highly desirable to so locate as to direct theentering tioning the vent the discharge the vent outlet that the userdoes not come into bodily contact with the discharge and by so posiisreadily diflused in the compartment with little likelihood that the userwill come accidentally near the outlet to sufier physical burns orscalds from the discharge during the use or operation of the oven.

By venting into an adjacent compartment there is permitted a shortdirect passage which allows an unimpeded flow therethrough andeliminates the need of precooling the vapors in the passageway as wouldbe necessary where it is directly discharged externally oi the cabinetso as to prevent burning or scalding the user working about the range.

While I have shown and described the preferred forms of my invention, Ido not wish to limit myself to the precise details as shown but wish toavail myself of such variations and much flcations as may come withinthe scope of the appended claim.

I claim:

Range apparatus comprising an outer casing. an inner casing forming achamber and being arranged so that it is in spaced apart relation to theouter casing, heat insulation between said casings, said inner casingforming an access opening to said chamber, a door for closing saidopening and having a portion set away at the lower part thereof from thelower part of said opening to form a restricted air inlet passage tosaid chamber, a heating element in said chamber extending from adjacentsaid restricted opening to the rear of said chamber, abaflle over saidheating element for directing the flow of incoming air over said heatingelement. and venting means in the upper rear portion of said innercasing above said baiile for venting said air into the interior of saidouter casing.
